Go GraphQL

GraphQL moves query planning to the client. That is the feature and the danger: one innocuous query can become ten thousand database round trips, and one over-permissive field can leak another tenant's data. Both are solved at the server, not in the schema review.

1. Schema-First with gqlgen

The .graphql schema is the source of truth. gqlgen generates models, resolver stubs, and the execution layer from it.

go get -tool github.com/99designs/gqlgen
go tool gqlgen init      # once
go tool gqlgen generate  # after every schema change
